A Brief History Honeywell Analytics: Founded in 1959 by Joshua Seiger, began as a gas detection manufacturer for the industrial boating industry and gained recognition by developing a gas detection system for Shell’s operations. In 1980, it entered the flammable gas market and was later acquired by Zellweger Analytics, which facilitated further expansion and the development of the company’s first carbon monoxide detector. In 2005, Honeywell Analytics was acquired by Honeywell International, cementing its status as a leading provider of reliable and effective safety solutions, particularly in the field of gas detection and protection.

Honeywell XNX Universal Transmitter Features and Benefits

xnx xnx transmitter gas detection system designed to identify flammable gasses and provides the following key features:

  • Flammable gas detection 0 to 100% LFL/LEL: This means the system can detect the presence of flammable gasses in a range from 0% to 100% of the Lower Flammable Limit (LFL) or Lower Explosive Limit (LEL). This wide range ensures it can detect even small traces or high concentrations of flammable gasses, offering comprehensive coverage.
  • Flexible operation options: The system provides various ways to operate or configure it. This flexibility allows users to adapt the system to their specific needs or the conditions of the environment where it’s installed. For instance, it might include adjustable sensitivity settings, alarm thresholds, or output options to integrate with other safety systems.
  • Minimal training required: Using this gas detection system does not  demand extensive training. It is designed to be user-friendly, allowing operators to understand and use it with ease. This reduces the time and resources needed for training, making it accessible to a broader range of users.

Advantages of  Xnx Universal Transmitter Honeywell

High Performance

Xnx honeywell analytics 4x5x5 excels in detecting flammable gasses from 0 to 100% LFL/LEL, and its Point IR technology with heated optics ensures it is resistant to contamination and hidden faults. Open-path IR detection for flammable gasses is also supported. The electrochemical cell provides precise toxic gas detection in parts per million (ppm), and the IR cell monitors both CO2 and combustible gasses reliably, even in harsh and explosive environments.

Flexible Operation

With three versions accommodating various gas detection methods, xnx transmitter honeywell x is versatile. The Multi-Purpose Detector (MPD) supports multiple sensor types and can be serviced in the field. It uses the standard 4-20mA with HART communication and offers Enhanced Device Description Language (EDDL) software. Multiple communication options, including up to three relays, MODBUS, and FOUNDATION Fieldbus, make it adaptable to different setups. There is also an option for a local IS port for handheld HART configuration.

Easy to Use

The XNX features a user-friendly interface with a large, backlit LCD display, which uses visual icons and colored buttons to present gas and sensor readings clearly. It supports eight different languages for accessibility. Self-test and fault indication features enhance reliability, and it’s designed for easy, non-intrusive one-person operation. Quick calibration with auto-inhibit further simplifies maintenance.

Easy to Install

Its 3 or 4 wire operation and multiple configurations (source, sink, or isolated) make installation straightforward. Plug-in sensors and replaceable cells reduce downtime. The NEMA 4X IP66 rating ensures it’s suitable for rugged indoor and outdoor use, and five conduit entries simplify the installation process.
